Indian authorities have detained dozens of Kashmiri activists and placed separatist leaders under house arrest to prevent them from holding anti-India protests to mark the anniversary of a top separatist leader's hanging more than three decades ago.

Shops and businesses remained shut Thursday and a curfew was in effect in some areas of Srinagar, the main city in Kashmir, after a strike was called by separatists.

Most people stayed indoors while hundreds of armed police and paramilitary soldiers patrolled largely deserted streets blocked by razor wire and barricades.

Pro-independence leader Mohammed Maqbool Butt was hanged in 1984 after being convicted of killing an Indian intelligence officer.

Anti-India sentiment runs deep in Kashmir where rebel groups have fought since 1989 for independence or a merger with neighboring Pakistan.
